ABSTRACT:
A particulate trap filter regenerative system for eliminating the fullness of particulates to a particulate trap filter, which collects particulates in the exhaust gas of diesel engines and the like, by burning off the particulates causing the loading with the flame injected from a burner disposed on the upper flow side of the filter, wherein the burner is installed in such a way that the flame injection axis thereof crosses with the extension line of the axis of the particulate trap filter at an angle of 35 to 55 degrees and a flame distributor provided with plural through holes is disposed in such a way that it crosses with the extension line of the axis of the particulate trap filter at an angle which is greater by 10 to 20 degrees than the flame injection angle of the burner. A honeycomb disc body made of ceramics may be installed between the flame distributor and the particulate trap filter.
